PROBLEM TO BE SOLVED: To reduce interface signal amount between a baseband unit and a remote wireless unit in an OFDM wireless machine, while suppressing deterioration of signal quality, especially, increase of signal processing scale in the remote wireless unit.SOLUTION: A baseband unit has a first sample frequency conversion unit performing first sample frequency conversion for down-sampling a transmission signal transmitted via an interface. A remote wireless unit has a second sample frequency conversion unit for up-sampling a signal received via the interface. The baseband unit has an inverse Fourier transform unit generating a transmission signal by inverse Fourier transform, and a transmission side compensation unit which compensates for the frequency characteristics of the first sample frequency conversion and the second sample frequency conversion. |
